Two Botrytis cinerea isolates, field captan-resistant and normal type, were grown in liquid medium for 4 days prior to captan application. The glutathione (GSH) and oxidized glutathione (GSSG) of their mycelium and medium were analyzed at various times during the fifth day of their growth. Only slight differences in GSH levels between the isolates were observed, but marked differences in mycelial GSH were found in response to captan. Following the application of captan, less GSH was produced and after a longer lag period by the normal type of the fungus compared to the resistant isolate. This increase in the GSH level in the resistant isolate could make more nonvital thiol compound available for detoxifying captan and therefore prevent damage the fungicide could cause to the vital protein thiols of fungal cells. © 1984.
